Active DI box for converting high impedance instrument outputs to low impedance line signals for feeding directly into a mixing console. Internal buffer amplifier to boost the signal, avoiding losses in long cable runs and 3-way pad switch for level matching. Ground-Float-Lift selector enables signal ground isolation with or without RF/mains filtering. Powered by 9-52V phantom power, optional 9V battery or 12Vdc adaptor Ground float option for ground lift with RF/mains filter Ground lift option isolates signal ground without filter 3 pad settings for level matching Power supply -9V battery (PP3 not supplied), 12Vdc adaptor (optional) or 9-52V phantom power Input - 6.3mm jack (unbalanced) Outputs - XLRM (balanced), 6.3mm jack through (unbalanced) Input impedance - >100k Ohms Output impedance - 600 Ohms Controls - 0/-20/-40dBu pad & Ground-Float-Lift switch Dimensions -103 x 70 x 45mm Weight - 243g
